process?

Run Server Version 3.x Professional, Advanced and Enterprise
Editions can be upgraded to JRun 4 provided that the number
of CPUs in the upgrade license match the currently installed
number of JRun 3.x CPUs. During the installation process
of the JRun 4 upgrade license, the installer will search

JRun 3.x serial number that is licensed for the same number
of CPUs.
